Solution. We see that the function is not constant on any interval. The function is increasing where it slants upward as we move to the right and decreasing where it slants downward as we move to the right. The function appears to be increasing from \displaystyle t=1 t = 1 to \displaystyle t=3 t = 3 and from \displaystyle t=4 t = 4 on.So pick the value inside each interval that is easiest to plug in and determine if the second derivative is positive or negative. If it is positive then the function is concave up on that interval, and if the second derivative is negative then the function is concave down on that interval. Just be careful to plug into the correct function.

Definition of Convexity of a Function. Consider a function y = f (x), which is assumed to be continuous on the interval [a, b].
